Question 1

A patient in renal failure needs to undergo testing to assess her electrolyte balance and need for hemodialysis.Which test would be most appropriate for this purpose?

Accepted Answer

Magnesium levels can become imbalanced in renal failure, and testing can help determine if the patient needs hemodialysis. Methemoglobin, microalbumin, and myoglobin testing would not provide relevant information in this situation.

Question 2

When assessing the significance of a patient's serum creatinine level, which factors should a nurse identify as being important? Select all that apply.

Accepted Answer

Serum creatinine levels are influenced by a patient's age, as kidney function can decline with age. Skeletal muscle mass is a significant factor because creatinine is a breakdown product of muscle metabolism; more muscle mass generally means higher baseline creatinine levels. Traumatic injury can also affect creatinine levels due to muscle damage and the potential for acute kidney injury. Level of activity, while important for overall health, does not directly influence serum creatinine levels in the same way as the other factors.

Question 3

When performing a venipuncture on a 2-year-old who is hospitalized, which actions by a nurse are most appropriate? Select all that apply.

Accepted Answer

The answer of When performing a venipuncture on a 2-year-old...

Question 4

A patient is suspected of having disseminated intravascular coagulation (DIC).Which test would be most appropriate for confirming this suspicion?

Accepted Answer

The most appropriate test for confirming DIC is protein S testing. In DIC, there is abnormal activation of the coagulation cascade, leading to widespread clotting in blood vessels throughout the body. This can cause depletion of protein S, which is a natural anticoagulant. Therefore, testing for protein S levels can help confirm the diagnosis of DIC. Potassium and total protein tests are not specific for DIC, and while urine protein testing may be useful in certain situations, it is not a primary diagnostic test for DIC.

Question 5

While working with a 10-year-old boy who is having a well-child checkup, the nurse would expect which of the following findings when inspecting the ear using an otoscope? Select all that apply.

Accepted Answer

B) A cone of light should be noted at the 5 o'clock position on the right ear and the 7 o'clock position on the left ear in a normal tympanic membrane.
D) The tympanic membrane should have a shiny pearl-gray color in a normal examination.
F) The external auditory canal should be an S-shaped canal lined with fine hairs in a normal examination. 
A bulging tympanic membrane (A) could indicate middle ear infection, while a retracted tympanic membrane (C) could indicate Eustachian tube dysfunction. A red and swollen pinna (E) may indicate inflammation or infection.

Question 6

The nurse would counsel which of the following individuals for an increased risk for kidney stones? Select all that apply.

Accepted Answer

Individuals with Crohn's disease, celiac disease, diabetes, and cirrhosis are all at increased risk for kidney stones due to factors such as dehydration, altered calcium metabolism, and kidney function impairment. Family history of renal cell carcinoma or history of glioblastoma do not increase the risk for kidney stones.

Question 7

A patient has a vitamin B₁₂ level of 120 pg/mL.For which clinical manifestations should a nurse assess this patient? Select all that apply.

Accepted Answer

Vitamin B12 deficiency can lead to fatigue due to anemia, a sore tongue due to glossitis, and weight loss due to appetite changes. Hyperreflexia and insomnia are not typically associated with vitamin B12 deficiency.

Question 8

The nurse is caring for a patient scheduled for an open lung biopsy of the right apices.Which of the following patient statements indicates that teaching has been effective? Select all that apply.

Accepted Answer

The answer of The nurse is caring for a patient...

Question 9

A nurse is positioning a patient for proctosigmoidoscopy.Which position should the patient be placed in?

Accepted Answer

The left lateral decubitus position is the most appropriate position for proctosigmoidoscopy as it allows for optimal visualization of the rectum and sigmoid colon. Additionally, it permits easy insertion of the sigmoidoscope without causing discomfort to the patient. The other positions listed, supine, semi-Fowler's and lithotomy are not ideal for this procedure.

Question 10

During a brain magnetic resonance imaging procedure, a patient complains of nausea.Which of the following should the nurse do in response?

Accepted Answer

Instructing the patient to take slow, deep breaths can help alleviate nausea and is a non-invasive, immediate response that can be implemented during an MRI procedure without interrupting it.

Question 11

A patient's laboratory test results indicate a positive finding on the mumps serology test.The nurse understands that this condition involves infection of which of the following?

Accepted Answer

Mumps is a viral infection that involves inflammation of the parotid glands.

Question 12

A nurse is providing nutritional and exercise teaching to a patient at risk for coronary artery disease.The patient demonstrates elevated low-density lipoprotein (LDL)cholesterol levels, blood pressure of 145/92 mm Hg, a body mass index (BMI)of 31, and normal triglycerides.Based on these findings, which of the following should the nurse recommend? Select all that apply.

Accepted Answer

Option A is incorrect as increasing sodium intake would be contraindicated for a patient with elevated LDL cholesterol and hypertension. Option E is incorrect, as alcohol in moderation has been shown to have some health benefits, and eliminating it entirely may not be necessary. 
Options B, C, and D are correct recommendations for a patient at risk for coronary artery disease. Losing weight and achieving a normal BMI can reduce the risk for heart disease. Engaging in moderate aerobic activity three to four times per week can also help reduce the risk for heart disease. Adhering to a heart-healthy diet is important for lowering LDL cholesterol levels and improving cardiovascular health.

Question 13

The nurse is caring for a patient who will undergo an adrenal gland scan.Which of the following would be included in the teaching? Select all that apply.

Accepted Answer

The adrenal gland scan involves injecting a radionuclide dye (A) to help diagnose conditions like Cushing's disease (B). Images are taken over several days (D) as the dye attaches to cholesterol in the adrenal glands (E). A full bowel cleansing (C) is not typically required for this test.

Question 14

The nurse would expect to find abnormally high results for urine protein in the charts for which of the following individuals? Select all that apply.

Accepted Answer

The answer of The nurse would expect to find abnormally...

Question 15

The nurse assisting in the care of patients receiving radioactive iodine uptake testing recognizes that which of the following can alter test results by decreasing radionuclide uptake? Select all that apply.

Accepted Answer

The answer of The nurse assisting in the care of...

Question 16

A patient is at great risk for renal failure and needs to undergo testing to evaluate his renal function.Which test would be appropriate for this purpose?

Accepted Answer

Phosphorus is a common laboratory test used to evaluate renal function. Renal function can be determined by measuring the amount of phosphorus in the blood, as the kidneys are responsible for filtering and excreting phosphorus from the body. high levels of phosphorus in the blood may indicate poor renal function, whereas low levels may indicate certain kidney disorders or other health conditions.

Question 17

A nurse is assessing a patient who has just undergone thoracentesis for pleural fluid analysis for symptoms indicating the development of pneumothorax.Which of the following are associated with this condition? Select all that apply.

Accepted Answer

Dyspnea, anxiety, and restlessness are all common symptoms associated with the development of a pneumothorax. Bradypnea and increased breathing sounds are not typically associated with this condition.

Question 18

The nurse is caring for a patient with a total cholesterol level of 267 mg/dL.Which of the following instructions should be included in the patient teaching? Select all that apply.

Accepted Answer

B) The patient should cut down on the number of eggs they eat each week, as eggs are high in cholesterol.
C) Lean meats like chicken and fish should become a bigger part of the diet to replace higher fat meats.
E) Dairy products are high in both fat and cholesterol, so the patient should be cautious with their intake. The other options are either not specific to cholesterol control (A and D) or not entirely accurate (F, as bread and grains are not typically high in cholesterol).

Question 19

Which of the following individuals receiving a transfusion would most likely receive blood that had been tested or screened for cytomegalovirus (CMV)? Select all that apply.

Accepted Answer

The answer of Which of the following individuals receiving a...

Question 20

A patient's laboratory test results indicate an increased level of lactic acid.This finding is consistent with which of the following conditions? Select all that apply.

Accepted Answer

Increased levels of lactic acid can be found in conditions where there is inadequate oxygen delivery to tissues or increased demand for oxygen that exceeds supply. This can occur in heart failure (B) due to poor blood circulation, in shock (C) due to reduced blood flow, and during strenuous exercise (D) due to high muscle activity outpacing oxygen supply.
